a corporation of Delaware i Application Mayll, 1942, Serial No. 442,499 zoiaims. (error-6) n struct the wheel that it provides sufficient space, within the confines of the tirecarrying rim to re'- ceive a powerful brake with clearance between the rim and brake; and to so construct the wheel that it can readily withstand the braking torque.

With these andotherobjects in view, the invention resides in the novel features of construction and combinations and arrangements of parts as more fully hereinafter set forth.

In the drawing 9 Figure l is a side elevation of a wheel embodying the invention;

Figure 2 is a cross section on the line 2-2 of Figure 1.

The wheel is designed particularly for use on airplanes and comprises the hub I, the inboard and outboard side elements 2 and 3, respectively, mounted on and fixedly secured to the, hub, the annulus 4 mounted on and fixedly secured to the side elements and forming with the radially outer portions thereof a tire carrying rim, and the reinforcing element 5 extending between and secured to the side elements. The hub l is formed of steel and preferably from a circular sheet steel blank by a series of drawing and upsetting and machining steps. The hub I is tubular and has the reduced central portion 6, the enlarged inboard and outboard portions 1 and 8, respectively, at the ends of the central portion, and the reduced outboard end portion 9. Suitable anti-friction bearings are arranged within the portions 1 and 9 for mounting the wheel upon the axle l0.

Each of the inboard and outboard side elements 2 and 3 is in the nature of a sheet steel disc preferably formed by die-pressing flat circular steel blanks. Each element has a generally radially extending body portion H and a rim portion 12 integral with the body portion. Each body portion II has a central axial part l3 fixedly secured to one of the enlarged portions 1 and 8 of the hub, a main part II, and a peripheral flared part I5. The main parts of the body portions converge radially outwardly and the peripheral parts diverge radially outwardly. Each main part is formed with an annular series of bosses l6 for attachment to a rotatable part of the brake I1.

The rim portions I2 diverge radially outwardly from the peripheralnparts l5 and each rim portion is formed witha flared. part l8 connecting integrally into a peripheral part, a generally axial bead seat l9 extending from the flared part-l8; and a generally radial hollow tire retaining flange or bead Zflextending from the bead seat I9, The 1 construction of each of the side elements as thus far described is the same. 10

cally in forming the outboard side element with the terminal radial flange 2| on the central axial part l3 andwith the valve stem; hole 22 in the flared part l8. Alsoythe bosses 16 of the inboard side element are apertured for the passage of the bolts 23 used in mounting the brake I Ton the wheel, itbeingnoted that the rim portion of the inboard side elementuis of a size and arranged so, that a clearance space is provided between the 9 and is dished, or of generally conical section,,,,and

it extends between and is connected to the flared part l8 of the inboard side element 2 and the I inner edge and, more specifically, the central axial part 13 of the outboard side element 3. Theangle of the dished or generally conical portion is the same as that of the flared part l8 of the inboard side element so that its radially outer attachment portion fits the flared part I8 and is readily sea cured between this flared part and the flared end a portion 24 of the annulus by the rivets 26, it being noted that the flared end portion 24 extends beconical portion of the reinforcing element is preferably provided with the holes 29 for decreasing the weight.

With this construction, the reinforcing element provides the necessary reinforcement for the wheel to withstand the radial and axial thrusts to which the wheel may be subjected in use. 4 Also, the dished reinforcing element, it will roFF They differ specifl The annulus cooperates with tral axial part of this inboard side element and. secured to the wheel hub by the rivets which A secure the inboard side element to the hub.
